Secure Boot will not function, Looking for BIOS Recovery/Update for RZ09-03519

Hey there,
I have a Razer Blade 15” (2020), RZ09-03519 model laptop that has started to have some strange power down issues, as well as some issues with booting up into Windows with Secure Boot enabled. Anytime I do enable it, it gives me an invalid signature error and will refuse to boot at all. From everything I have read, this will require at least a BIOS recovery, if not a full on BIOS update, and I am unaware of how to get such a thing. I checked the laptop’s BIOS and Firmware page and there have been no BIOS updates for this model listed. I feel like just a recovery would work just as well, but have had no luck in finding anything about that either.

Is there a possibility for someone from Razer to reach out with a link to at least a recovery I can do with this thing? Or should I look for a BIOS for the specific CPU? Where do I go from here? Thanks.

    Hey there, ​@technoPompAndPower165 

    I understand that your Razer Blade 15 (2020) is experiencing power-related issues and displays an "Invalid signature" error when Secure Boot is enabled, preventing Windows from booting properly. 

    Could you please provide a photo or video showing the issue so I can take a closer look and attach it to your case? Additionally, please send me a private message with your device's serial number so I can check its details in our system and assist you further.

    You can upload the photo/video using this link and then send me a PM with the link once it’s uploaded. Thank you!
